The block is made for droping heavy loads on a rope like when chunking down a tree or topping it.A pulley is made for smoother operation where the rope is not slammed just pulled slowly!

I saw one of your posts that stated you have been in the biz for 10 yrs. In another thread you argued that screw type biner's were safer to use in your climbing set up than triple locking biner's, now you state that you think blocks and pullys are the same. This is the 101 forum, people are here to learn and get GOOD advice. Stop posting this crap that turns the whole thread in a direction that does nothing for the op.
To the OP: The first block i ever purchased was a CMI. Good strength, good price, and easy to use. I buy my rigging equip from Wesspur.

All those are listed as pulleys, except for the "Double Pulley Block" pulley.
Other than rigging points(such as a trolley pulley), the only differences I can see is their strength.
So I'm happy with the healthier, stronger, smarter system of determining when a pulley becomes a block.
That's what's important; Right? Making sure you only drag enough gear into the tree to carry the load beyond and chance of failure and nothing more.

I never stated that I think blocks and pulleys are the same, I stated that I heard that blocks and pulleys are the same. Now I'm trying to work out the difference.
Flush out your head gear!

Thanks for posting the vid, but youtube ain't happening on dialup.
But hey, isn't that a sling he's using?
Yup it is a sling

That link doesn't want to load for some reason. We're in the middle of a non-existent snow storm here that may be affecting my connection. Maybe that's why I only got 1 page from Sherrill.
Anyway,
Yeah, there's nothing like saving a buck or two, especially when your life is hanging in the balance.

when I click the link i get 3 pages... try just going to sherrill's site, rigging, then blocks and pulleys (in the drop down menu)
how many people use a biner to attach the block to sling? cause what we use ours for would break that no doubt. We have about 8-10' of 1" or 1 1/4" with a spliced eye on one end that we use

I would and do use a sling with biner to hold 4" pulley for some rigging, but it holds up to that... I dont think I would use a set up like that on a block. The metal on metal would bother me, I would not want to mar or damage the attachment sleeve. For me arborist blocks get tied on with rope or sling only no metal.
I don't believe those are biners but hoist rings. The solid rings and sling are used in crane work.

I wonder why he's using those aluminum ******* instead of just choking the sling through the eyes? love the dew though, reminds me of someone..
I agree. I'm sure it works fine but I would be thinking about damaging the sheave on my block.
